title: [Antigen L, a new antigen from tubercle bacilli active in delayed hypersensitivity in animals sensitized with living bacilli (B.C.G.)].
abstract: This report described the occurrence of an antigen in the tubercle bacilli. The antigen, designated antigen L, was mainly active in delayed hypersensitivity reaction in Guinea Pigs sensitized with living bacilli such as the B.C.G. strain.
